Application fil ed October 11,1928. Serial No. 311 ,5316". i

My invention relates tofurnace wall construction and. particularly to walls of the socalled suspended type inwhich horizontally extending sections thereof are supported independently of the sections above and below.

It especially relatesto the form of construction and means wherebysome or all of the individual blocks comprising. the wall are positi ely anchored in po i and y maybe i 1 easily removed and. replaced when necessary- The objects of my invention are to provide a furnace wall" of thetype commonly known as suspended in which an improved method offanc horing the separate blocks is'employed.

" 'Afurther object is to provide a means for positively anchoring the blocks inthe wall without substantially weakening the block itself or impairing its heat resisting characteristics. A further object is to provide a wall 120 which in any individual block orseries of blocks may be comparatively easily removed and replaced when necessary.

lVith these and other objects in view which will appear as the description proceeds, my

invention includes the novel elementsand the combinations and arrangements of elements described below and illustrated in the accompanying drawing, in Which Fig. 1 is a fragmentaryperspective view of my preferred form of wall; H

Fig. 2 is a fragmentary perspective View of a slightly modified type of wall embodying certain'features ofmy invention;

Fig. 5 is a perspective view illustrating a detail. 7 7

Referring to thedrawings, my wall comprises a metalframe including vertical posts or columns, 1, to which are connected horizontally extending elements, 2, adapted to form independent supports for separate sectrons of the wall. Bolted, or otherwise secured to the members, 2, are shelves or brackets, 3, each of which forms a narrow,horizontal platform extending outwardly from the top of element, 2, and adapted to "form a support for a vertical section of'the'w'all; These brackets are horizontally spaced from each other, on centers, a distance equal to the width of the'blocks which are torest thereon, and are provlded with supporting legs o'r-braces,

l, restingupon thelower fiangesof'thehorizontalmembersi a 1 i Extending between Vertically "spacefdi shelves, is an e1ement,*5, "preferably? but "mean necessarily, a T-section. The extremities 6f elements, 5, preferably extend into slots, "6, provided in the shelves, 3, and are thus interlocked with the shelves to the extent that'they cannot be directly pulled outwithoutfirst "l6 raising the elements sufliciently to disengage their lower extremitiesfroin the slots. 7 Referring now toFig. 4:,itwillbe apparent that the ends of the elements, 5,; are not out squarely'across. For example, at the upper70' end of each T-section'the flange. is out be, as shown at 7, while the web extends somewhat beyond'thepoint where the "flange is cut off, as shown at 8, and a narrower portion'of the web extends still'further as shownat 9, :s074$v that it entersthe slot, 6, in shelf, 3. At the bottom, the flange extends somewhat be yondthe web, as shown at 10, so thatlit enters the slot, 6, in 1owershe1f,3, and the webis notched, as at 11, so that the projecting per-" tion, 9, of the next lower element, 5,'m'ay be j pushed upwardly and enter therein. It will be apparent from an examination of'Fige that the T-shaped slots in the shelves, 3, while y of sufficient width to receiv t flange the elements ,5, the stem portions; of the'T-1 slots are-not long enough to receive the'en- "tire web portions. In other words, theportion, 12, of the webrests upon the upper, Sup. face of, the shelf, 3. Thepur'po f cutting,

-' the ends of the elements-5, in thisway is to "provide not only for interlocking them with V i "the shelves, 3, but also for easily removing them: 'fToremove anyverticalelementit is only necessary tolift it slightly so 'that 'theiib flange is raised from' the slot in the shelf at the bottom, whereupon it may: be pulled for,- wardand out of theframe;

' In the preferred'typeof wall,eael b lock, at the rear, is p'rovided with a shallow recess,"1

13, in the top surface thereof. This recess may be T-shaped, as shown in Figs. 1 and 3, and have the base of the T opening lying in the rear face of the block. Resting in these recesses-and engaging the flanges of the vertical elements, 5, are the anchors or ties, 14. These anchors are simply slipped over the tops of the elements, 5, where the flanges are gout off and allowed 'to slide down the flanges anchored; Intermediatethese blocks, ordinary fire bricks or blocks, 17, may be used without positive anchorage, as shown; in Fig.v 2. a

Horizontal expansion of the wall may be A provided for by leaving larger, vertically extending jointsat properintervals and filling these joints with asbestos, clayor. other soft imaterialwhich is well known and approved the art offurnace construction. 7 Vertical expansion is provided for by joints, 18 and 19,

of such material, between each horizontally extending section of the wall, k

In the broader aspects of my invention, no particular form or size of brick or block is contemplated so long as it is provided with an anchoring recess in the top. or bottom. The designof the anchoring and supporting device is such as to accommodate practically any type of block'provided with anchoring recesses'therein. Furthermore, it will be apparent that the anchors. themselves and the recesses in the blocks need not be of the precise shape shown, itbeing sufficient that a recessand anchor of suchcliaracter be providedthat they cannotbe separated except by-vertically lifting the anchor or block. If

desired, the blocks may be provided-with tongues andgrooves as shown in Fig. 3. 7

While I have described my invention in its preferred embodiment it is to be understood that the words which I have used are words of description rather than of limitation, and

that changes-within the purview of the appendedclaims may be made without depart- 7 ing from thetrue scope and spirit of my inp 7 ventionin itsbroader Y 'WhatI, claim I is-- I v I 1. In a furnace wall, the combination with a'metal frame comprising vertically spaced,

horizontally extending. members forming independent supports for horizontally extending sections of said wall and vertical elegments extendingbetween said firstmentioned -members, offlafacing comprising spaced rel fractoryblocks, means positively engaging saidjbl'ocks and said vertical elements to tie said blocks 7 and :frame together, and. refrac- HOW frame provided with vertically spaced,horizontally extending members forming inde frame and facing together.

tory facing bloc-ks filling the space intermediate said tied blocks to form a complete covering for said frame.

2. A furnace wall comprising a metal frame provided with vertically spaced, horizontally extending members forming inde pendent supports for horizontally extending sections of said wall, a facing comprising refractory blocks provided with recesses supported on said members, vertical elements extending between said horizontal members, and anchors engaging said vertical elements and said blocks in the recesses.

3. A furnace wall comprising a metal pendent supports for. horizontally extending sections of said wall, a refractory facing for said wall comprising blocks supported on said members, vertical elements extending:

between said members, and anchors slidably engaging said elements and provided with portions interfitting with the blocks in com-- plementary recesses provided in said blocks for tying the facing to the frame.

In a' furnace wall, the'combination with a metal frame comprising vertically spaced, horizontally extending members forming in dependent supports for horizontallyextend= ing sections of said wall, of a facing com-1 prising refractory blocks supported on said members, vertical elements extending between said members and interlocked there-.
